Went out garage saling for a local 50 mile garage sale. After a couple of hours of nothing I found a sale back in the woods a bit that was really clearing out the stuff. On one trailer was a box of dirty common insulators so naturally I dug through it to see what I could find. This was the best piece by far. I have been looking for one of these C N R marked brown Pittsburghs for about 10 years. No luck at shows or anywhere else. Then this turns up. The mark is doubled and slightly rotated but it is obviously a C N R and it's in pretty much mint condition. I couldn't make it to the National but this is a great substitute.
